Be Your Own Souvenir So you’re at the museum, and deep down in the sub-basement right next to the restrooms you happen to discover an enormous machine that looks like it was pulled from the Aliens II movie set. And then you notice you can insert a dollar, and suddenly the machine whirs to life and pipes hot, neon green plasticine into a mold in front of your very eyes as you inahale noxious fumes. Within moments you’re in the possession of a bona-fide neon green submarine, a memento of your visit to the museum that smells strange for days. Be Your Own Souvenir by Barcelona-based blablabLAB is just like that, except a trillion times more awesome. Using custom software developed using openFrameworks and openKinect, visitors film themselves in front of 3 kinect sensors for a full 360-degree scan and within moments a 3D printer known as a RepRap machine spits out a little army guy version of themselves.
How to Make Char-Twine Hubble: Where is the center of the Universe? When astronomers look at distant galaxies to determine how fast they're moving, it looks like they're all moving away from us. Does that mean we're at the center of the universe? Well, no. It turns out that every point in the universe sees itself as the center! Try this! - Use your mouse to drag the top (blue circle) layer randomly over the bottom one, the difference between the two is hard to see. - Now choose a different dot on the top layer and line it up with its corresponding dot on the bottom layer. What's going on? The top layer (the universe today) was made by enlarging the bottom layer (the universe 1 billion years ago) by 5% percent.
Tap code The tap code, sometimes called the knock code, is a way to encode messages, letter by letter, in a very simple way and transmit it using a series of tap sounds, hence its name. It has been commonly used by prisoners to communicate with each other. The method of communicating is usually by "tapping" either the metal bars, pipes or the walls inside the cell. Design[edit] The tap code is based on a Polybius square, a 5×5 grid of letters representing all the letters of the Latin alphabet, except for K, which is represented by C. Or to communicate the word "water", the cipher would be the following (the pause between each number in a pair is smaller than the pause between one pair and the next): Because of the difficulty and length of time required for specifying a single letter, prisoners often devise abbreviations and acronyms for common items or phrases, such as "GN" for Good night, or "GBU" for God bless you.[1] History[edit] References[edit] External links[edit]
DIY Polygraph Machine: Detect Lies with Tin Foil, Wire and Arduino DIY Polygraph Machine: Detect Lies with Tin Foil, Wire and Arduino Lying is awesome. From a very young age, children learn that flat out denying the truth gets you out of trouble and helps keep you calm in the face of horror. But what happens when you just have to know if someone, say, used your toothbrush? You could ask them to take an expensive and arduous polygraph test. If you're industrious and don't have the dough for a legit polygraph, you can make your very own galvanic skin response (GSR) device. Today, we will make a cheap GSR device and learn if our toothbrush is really safe after all. Materials ArduinoAluminum foilVelcroWire10k resistorBreadboard Step 1 Make the Electrodes GSR machines require an even and consistent connection to the skin in order to function properly. Begin by taping the exposed end of a wires to a sheet of foil. Adhere a strip of Velcro over the tape and cut off the extra foil. Last, add a single piece of Velcro at the end of the foil side. Step 3 Load the Code
Symphony of Science From Terminator to Pollinator: Bees Go Robotic - Technology Robotics engineers are buzzing about a machine with potentially transformative implications for agriculture, surveillance, and mapping: the "robobee." Researchers at Harvard’s School of Engineering and Applied Sciences plan to have the mechanized critters flapping though the air autonomously within the next three years, according to NPR. And if coaxing the machines into flight isn't enough of a challenge, the real innovation lies in getting the machines to mimic the collaborative behavior of a colony. Each robobee will be equipped with sensors and cameras, instead of antennae and eyes, that will allow them to do everything from pollinating a field of crops to searching for survivors after a natural disaster. Manufacturing the bees has required completely rethinking materials and process. Image courtesy of Pratheev Sreetharan
How to make a tool set Life without tools is barbaric. But even simple tools can be expensive in rural parts of developing countries. Import duties bump the costs up higher than they are in the States or elsewhere, and sometimes only low-quality brands are available anyway. So, to hold off future barbarians, we'd like to show how to build a simple tool set on a very low budget. Larry Bentley, the man who figured out how to make these tools, said a wise thing: "Without tools, kids don't take stuff apart, and without taking stuff apart, you don't learn how things work." These tools, Bentley says, could be in the hands of the next William Kamkambwa,who made a working wind power generator from backyard scraps in a village in Malawi. Here's Larry's quick guide to DIY tools. The tools in this guide: Saw Pliers Wooden vice Wood drill bit / star drill bit Chisel Strap hinge vice
Rosenhan experiment Experiment to determine the validity of psychiatric diagnosis Rosenhan's study was done in eight parts. The first part involved the use of healthy associates or "pseudopatients" (three women and five men, including Rosenhan himself) who briefly feigned auditory hallucinations in an attempt to gain admission to 12 psychiatric hospitals in five states in the United States. All were admitted and diagnosed with psychiatric disorders. After admission, the pseudopatients acted normally and told staff that they felt fine and had no longer experienced any additional hallucinations. All were forced to admit to having a mental illness and had to agree to take antipsychotic drugs as a condition of their release. The second part of his study involved an offended hospital administration challenging Rosenhan to send pseudopatients to its facility, whom its staff would then detect. While listening to a lecture by R. Pseudopatient experiment[edit] Non-existent impostor experiment[edit] See also[edit]
The Leap Remember how cool Tom Cruise was in “Minority Report” when he was manipulating computer data on a life-sized clear screen with his bare hands? Well, we may be approaching a similar plane of awesomeness once we adopt The Leap, which is itching to replace and outshine the good ol’ reliable but tired computer mouse. Big strides have been taken to make virtual reality more of a reality. Today we’re enjoying gadgets that have us believing that we’ve crossed over to the flipside. Video game consoles such as the Nintendo Wii and Xbox 360 + Kinect, and touchscreen tablets, smartphones, 3D televisions and movies have been eagerly embraced not only by geeks but by the general public. But they have us wanting more. What exactly is The Leap? Imagine what sort of Pandora’s box The Leap is opening up for those who work with and rely on 3D imaging; i.e. graphic artists, game developers, architects, scientists, doctors, engineers.
Top 10 Things You Can Upgrade with a Little Electronics Hacking it is a skill to do a good solder joint, it comes with LOTS of practice. so most people who rarely do it will ever get good at it. Bingo. Of course, part of the issue is having a soldering iron at the right temp with a properly tinned tip. Newbies aren't using soldering stations but a cheap iron they got at rat shack (You have questions? I don't expect to ever master tricky stuff like smts or even multilayer pcbs so I'm not much better then a newbie, anyway - and I totally suck at sweating pipe joints. Ah, well... SMT is actually a bit better than through-hole once you get the hang of it.
Depressive realism Evidence for[edit] Evidence against[edit] When asked to rate both their performance and the performance of another, non-depressed individuals demonstrated positive bias when rating themselves but no bias when rating others. Criticism of the evidence[edit] Some have argued that the evidence is not more conclusive because there is no standard for "reality," the diagnoses are dubious, and the results may not apply to the real world.[33] Because many studies rely on self-report of depressive symptoms, the diagnosis of depression in these studies may not be valid as self-reports are known to often be biased, necessitating the use of other objective measures.
